Partition mode support for disks

[xwr-ron]

Hi, I recently reinstalled my Arch Linux based system and finally decided to set up a snapshot system in a lux container.

I tried to add the path of the device I wanted to see in my bar at first, but later I realized that it was impossible, since the source code only works with a mount point

If I can find some free time, I can implement it

• Device path support (/dev/nvme0n1p3 or /dev/mapper/vg1-root)
• Thin and thick pool support (vg1-thinpool)
